Notes:
1: Just to make sure that I have noted it here, the latest
yum updates have been applied.
2: The mounting of LABEL=/share to /usr/share appears as a
drive on the desktop, unlike /usr, which does not appear.
This is quite annoying. Why is that it appears on the desktop?
1. Have have done what you have asked, above.
2. restorecon -vvR /usr
<no corrections were made>
3. clamav-milter:
+ was never started at boot. Logs show a permission problem with clamav.log
+ deleted: /var/log/clamav-milter/clamav.log
+ service clamav-milter start
<no more sealert permissions problems, it started up!>
[perhaps, the problem here is that an existing log file from
a previous startup, is no longer accepted and fails on the
next reboot unless clamav-milter service is shutdown, the
log file is deleted, before rebooting. This has been verified.]
4. spamass-milter:
+ The spamass-milter.sock orignally when created at reboot shows:
srwxr-xr-x sa-milt sa-milt system_u:object_r:spamd_var_run_t:s0 spamass-milter.sock
BUT, when restarting spamassassin, it shows a different user context:
drwxr-x--- sa-milt root system_u:object_r:spamd_var_run_t:s0 .
drwxr-xr-x root root system_u:object_r:var_run_t:s0 ..
srwxr-xr-x sa-milt sa-milt unconfined_u:object_r:spamd_var_run_t:s0 spamass-milter.sock
----------------------------^^^^^^^^^^^^
+ chcon -u system_u spamass-milter.sock
<has no effect, sealert continues>
+ chcon -t initrc_t spamass-milter.sock
<permission denied, even as root user>
5. I still have unresolved issues with the others:
rhgb, xorg, ifconfig, xdm-server
Any ideas, anyone?
